Application of green walls still has not attracted interest among the contractors and people, and this can be due to poor growing performance of the plants on these systems. This study investigated the effect of four growing media types (30% cocopeat + 65% perlite + 5% vermicompost, 30% soil + 65% perlite + 5% vermicompost, 30% mushroom compost + 65% perlite + 5% vermicompost and regular soil a...

industrial waste management is one of the most properly approaches which make industry and environment collaborating and coacting as well as reduce impacts of industry on environment. in this study, present management of yazd industrial township located in yazd province was studied. in order to properly manage and control waste production, questionnaires were used to collect data regarding type...

Representative biomarkers (e.g., n-alkanes), diversity and microbial community in the aquifers contaminated by high concentration of arsenic (As) in different sediment depth (0-30 m) in Jianghan Plain, Hubei, China, were analyzed to investigate the potential mechanism of As enrichment in groundwater. The concentration of As was abundant in top soil and sand, but not in clay. The analysis of the...

The conventional landfilling does not promote sustainable waste management due to uncontrolled emissions which potentially degrade the environment. In this regard, pre-treatment of municipal solid waste prior to landfilling significantly enhance waste stabilization and provides various advantages. So in this regard pre-treatment methods of municipal solid waste were investigated. The major obje...

In the present paper, nanosized TiO2 supported by zeolite was used in the ozonation of Songhua River as catalyst. The catalytic activity of TiO2/Zeolite for ozonation was testified by nitrobenzene removal, which is one kind of representatively resistant organic contaminant. And the removal of some organic and inorganic compounds existing in the Songhua River by TiO2/Zeolite catalyzed ozonation ...

OBJECTIVE To investigate phosphorus limitation and its effect on the removal efficiency of organic matters in drinking water biological treatment. METHODS Bacterial growth potential (BGP) method and a pair of parallel pilot-scale biofilters were used for the two objectives, respectively. RESULTS The addition of phosphorus could substantially increase the BGPs of the water samples and the ef...

--------------------------------------------------------ABSTRACT----------------------------------------------------------Pilot plant composed of fabric filters integrated with the decentralized treatment plant ZECUwas tested for its ability to remove the suspended solids and organic matters presented as TSS, CODt and CODs from wastewater. The filters were made from scrim polyester non-woven fa...
